Designing biochar properties through the blending of biomass feedstock with metals: Impact on oxyanions adsorption behavior

2018

Metal-blending of biomass prior to pyrolysis is investigated in this work as a tool to modify biochar physico-chemical properties and its behavior as adsorbent. Six different compounds were used for metal-blending: AlCl3, Cu(OH)2, FeSO4, KCl, MgCl2 and Mg(OH)2. Pyrolysis experiments were performed at 400 and 700 °C and the characterization of biochar properties included: elemental composition, thermal stability, surface area and pore size distribution, Zeta potential, redox potential, chemical structure (with nuclear magnetic resonance) and adsorption behavior of arsenate, phosphate and nitrate. Metalblending strongly affected biochars' surface charge and redox potential. Moreover, it incre…

Assessment of Five Monazite Reference Materials for U-Th/Pb Dating Using Laser-Ablation ICP-MS

2019

Monazite is a common accessory phosphate mineral that occurs under a wide range of pressure and temperature conditions in sedimentary, metamorphic and igneous rocks. Monazite contains high amounts of Th and U, rendering single monazite grains suitable for in-situ U-Th/Pb dating using laser ablation inductively-coupled mass spectrometry (LA-ICP-MS). Two key aspects of monazite dating that are critical for accurate age data with maximum precision are (i) optimized instrumental conditions to minimize analytical scatter and (ii) a well characterized reference material to ensure the accuracy of the obtained aged. Here, we analyzed five monazite reference materials (USGS 44069, 94-222, MAdel, Moa…

Las identidades de la crónica. Hibridez, polisemia y ecos históricos en un género entre la literatura y el periodismo

2017

28 Páginas Como todos los conceptos de frontera, el de crónica no resulta precisamente cristalino, en particular a la hora de encontrar una definición que despierte consenso o adquiera una cierta universalidad. Tratar de definir sus contornos constituye el objetivo de este artículo, que plantea un recorrido histórico para tratar de entender los diferentes matices que encierra. Bajo el paraguas de un término entre la literatura y el periodismo, híbrido y polisémico como crónica, se identifican tres tipos producciones. El análisis de las variedades periodísticas permite reconocer, en primer lugar, una modalidad ligada a la actualidad, de carácter más breve; en segundo lugar, producciones de l…

Towards a Blended Learning Model for Teaching and Learning Computer Programming: A Case Study

2008

Blended learning is becoming an attractive model in higher education as new innovative information technologies are becoming increasingly available. However, just blending face-to-face learning with information technologies cannot provide effective teaching and efficient solutions for learning. To be successful, blended learning must rely on solid learning theory and pedagogical strategies. In addition, there is a need for a design-based research approach to explore blending learning through successive cycles of experimentations, where the shortcomings of each cycle are identified, redesigned, and reevaluated. This paper reports on a study conducted on a blended learn- ing model in Java pro…

The role of informal learning in adults' literacy proficiency

2021

This study used the Programme for International Assessment of Adult Competencies (PIAAC) dataset to examine informal literacy learning’s effects on adults’ literacy proficiency. Also, the factors associated with informal literacy learning at and outside of work were studied. The study participants were Nordic adults aged 35–65 years. The statistical method was regression analysis, and the results indicate that informal literacy activities at work are associated primarily with occupation, and informal literacy activities outside of work with education, parents’ education and gender. Initial education, occupation, language background and age exerted the strongest estimated associations with r…

Language, culture and interculturality through narratives with learners of Spanish as a foreign language

2018

Aquesta investigació es basa en una experiència d’aula amb aprenents adults d’espanyol com a llengua estrangera. L’objectiu és aprofundir en el desenvolupament conjunt de competències lingüístiques, comunicatives i interculturals mitjançant l’escriptura. S’atendrà la competència comunicativa des d’una perspectiva intercultural, en un procés d’aprenentatge de l’idioma basat en reflexions socioculturals. El treball queda emmarcat dins el Projecte TALIS (Ensenyament i Adquisició de Competències Solidàries i Interculturals a través de les Llengües i de la Literatura). El resultat ha estat la publicació d’un volum de contes bilingües (espanyol-anglès), amb un enfocament lingüístic i intercultura…

Nota de les editores: Recerca actual sobre l’ensenyament de la gramàtica. Per a què serveix ensenyar gramàtica?

2020

La recerca sobre l’ensenyament de la gramàtica abasta temes diversos i adopta perspectives plurals. El III Congrés Internacional sobre Ensenyament de la Gramàtica (Congram19), celebrat a la Universitat Autònoma de Barcelona del 23 al 25 de gener de 2019, n’és una mostra. La presència de treballs de recerca actuals realitzats en diversos contextos va ser una oportunitat per a contribuir a un camp comú en el qual sigui possible reflexionar i debatre sobre les particularitats de la recerca realitzada en cadascun d’aquests contextos, lligada clarament a les finalitats assignades a l’ensenyament de la gramàtica. En aquest número especial es recullen les aportacions de 16 investigadors resultants…
